What is Red Light Therapy?
Red light therapy, also known as photobiomodulation or low-level light therapy (LLLT), uses low-level red or near-infrared light. It stimulates cellular function and offers health benefits. This non-invasive therapy is becoming popular for its healing, anti-inflammatory effects, and overall well-being.
Definition and Background
Red light therapy uses light in the red and near-infrared spectrum, from 600 to 850 nanometers (nm). This light positively impacts the body’s cells, especially the mitochondria. The mitochondria become more efficient, improving cellular function and health benefits.
Different Names for Red Light Therapy
Red light therapy is also known as:
- Photobiomodulation
- Low-Level Light Therapy (LLLT)
- Soft Laser Therapy
- Cold Laser Therapy
- Biostimulation
- Photonic Stimulation
These names all point to the same idea: using low-level light to boost cellular processes and healing.
“Red light therapy was accidentally discovered in 1967 by Endre Mester at the Semmelweis Medical University in Budapest, Hungary, who found that laser light helped promote hair growth and wound healing in rats.”
Since its discovery, red light therapy has been studied a lot. It’s now being looked into for many medical and cosmetic uses. See photobiomodulation devises here.
How Does Red Light Therapy Work?
Red light therapy, also known as photobiomodulation, uses light to help our cells heal. It works by using specific light wavelengths to boost cellular activity. This process involves the interaction between red and near-infrared light and the mitochondria, our cells’ powerhouses.
Mechanism of Action
Red and near-infrared light, between 630 to 850 nanometers, enters the skin. It’s absorbed by chromophores in the mitochondria. This absorption starts a chain of positive chemical reactions.
These reactions lead to more ATP, our cells’ main energy source. With more ATP, cells work better, tissues heal faster, and inflammation decreases. This is why red light therapy offers many health benefits.
Benefits of Red Light Therapy
- Improved collagen production, leading to reduced wrinkles and enhanced skin elasticity
- Reduced inflammation and scarring, promoting faster wound healing
- Pain relief for conditions like osteoarthritis and tendinitis
